小视频源码，关于鉴权你了解多少？

使用session/cookie

cookie.js

const http = require('http');
// 一般需要存到数据库里
const session = {}
http.createServer((req, res) => {if (req.url === './favicon.ico') {res.end('')}console.log('cookie', req.headers.cookie);const sessionKey = 'sid';const cookie = req.headers.cookie;if (cookie && cookie.indexOf(sessionKey) >= 0) {res.end('welcome back');const pattern = new RegExp(`${sessionKey}=([^;]+);?\s*`);const sid = pattern.exec(cookie)[1];console.log('pattern', pattern);console.log('sid', sid);console.log('session', sid, session, session[sid]);} else {const sid = (Math.random() * 89999).toFixed();// 设置cookieres.setHeader('Set-Cookie', `${sessionKey}=${sid}`);session[sid] = {name: 'izengx'};res.end('hi new one')}}).listen(3000)

session.js

const koa = require('koa');
const app = new koa();
const session = require('koa-session');// 使用redis存储session
const redisStore = require('koa-redis');
const redis = require('redis');
const redisClient = redis.createClient(6379, 'localhost');
const wraper = require('co-redis');
const client = wraper(redisClient);// 加密的key
app.keys = ['some secret'];const SESS_CONFIG = {key: 'kkb:sess',maxAge: '86400000',httpOnly: true,signed: true,   // 哈希签名store: redisStore({client}),    // 存储到redis
}// 注册
app.use(session(SESS_CONFIG, app))
// 验证是否存到redis了，把redis里存的值打印出来看看
app.use(async (ctx, next) => {const keys = await client.keys('*');keys.forEach(async key => {console.log(await client.get(key));});await next();
})app.use(ctx => {if (ctx.path === '/favicon.ico') return let n = ctx.session.count || 0;ctx.session.count = ++n;ctx.body = `第${n}次访问`
})
app.listen(3000);
